UNITED STATES RUPERT P. JENSEN, OF SEATTLE, WASHINGTON.

FIREPLACE HEATER.

Application filed July 25, 1928. Serial No. 653,628.

T all whom it may concern:

Be it known that I, Rornnr P. Jensen, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Fireplace Heaters, of which the following is a specification.

This invention relates to fireplace furnaces for heating rooms and buildings, and its objectis the provision of a heater of this character which has all of the advantages of an open'fireplace and a hot air furnace and which may be operated with a small consumption of fuel.

More specific objects and advantages of the invention will appear in the following description.

The invention consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawings,-

Figure 1 is a view, partly in front elevation and partly in transversevertical section, of my improved heating apparatus; and Fig. Qis'a longitudinal verticalsection of the same. I Figs. 3, 4 and are horizontal sections on broken lines 3-3, 44: and 5-5 of Fig. 2. I

'In said drawings, the reference numeral represents a chimney supported upon the foundation of a' building and extending upwardly through the floor 11 of a living room. Above said floor the chimney is provided with an open fireplace 12 having the usual throat 13 which communicates with a chimney flue 14. 15 represents a damper for regulating the eifective size of the throat 13. r

In the basement below the floor 11, the chimney structure is provided with a hotair chamber 16 containing a stove or fire box 17 which is supported upon partitions 18 which with the fire box divide the, loWer portion of said chamber into an ash pit 19 below the fire box and a passage 20 at each side of the fire box and communicate with the chamber space above the latter.

Screened inlets 21 provided in the side walls 22 of the chimney admit air from the external atmosphere into the respective passages 20 at an elevation below the bottom of the fire box. Thefire box is provided with an opening in its front through which fuel is supplied, said opening being provided with a door 23 which, as shown, is hinged at 24 and is adapted to be temporarily held in its open position as by means of counterweights such as 25 suspended by a cable 26 passing over a guide pulley and connected to the door.

A grate 27 is provided'in the floor of the fire box directly above the ash pit 19. 28 represents an ash chute extending downwardly from the fireplace and communicating at its lower end by means of a passage .65 29, Fig. 5, with the ash pit. A slidable door 30 is provided in passage 29 to prevent air entering into the ash chute and permits ashes to be removed through the ash pit and the opening 31 which is provided with a 70 door 32.

According to the present invention, the fire box 17 is provided with a stove pipe 33 having a branch outlet 33 into a flue 34: in the chimney'and, above such outlet, the stove 75 pipe has a connection 35 with a smoke and hot-air duct 36 having an outlet 37 through a wall of the fireplace into the latter. Above its outlet 33 the stove pipe is provided with an inlet branch 38'within the hot air cham- 80 her 16, the opening of said inletv branch having a damper 39 (Figs. 1 and 2) which is regulated by means of a cable 40 or an equivalent extending through the front wall of the chimney.

A damper 42 in the pipe outlet 33 and a second damper 43 in the stove pipe above the outlet 33 are respectively regulated by means of controlling rods 44 and 45 extending outside of the chimney structure.

1-6 represent hot air pipes extending from the hot air chamber 16 to rooms which are to be supplied with heat. These hot air pipes are provided with dampers (not shown) which may be in the nature of those 95 employed in the usual floor or wall registers.

A vessel 47 (Fig. 1) to contain Water is desirably provided within the hot air chamber 16 to furnish humidity to the air therein. 48 represents a pipe-coil provided in the fire box 17 to supply hot water for domestic purposes.

In the use of my invention, the stove 17 and the fireplace 12 may be operated either 10 separately or together by a suitable regulation of the several dampers. When the stove is employed, air admitted through openings 21 and passages 20 at opposite sides of the stove into the heating chamber 16 becomes hot by radial heat from thefire in the stove.

When a fire is started in the stove, the

damper 43 (Fig. 1) is closed and damper 42 opened to cause the smoke from the stove to be delivered into the chimney flue 34. With the dampers 42 and 43 thus arranged and by opening the damper39'the hot air from chamber 16 is permitted to escape through the passage 36 into the fireplace and is directed through the latter into the room containing the fireplace. When the hot air is thus delivered through the fireplace, the

V throat damper thereof is advantageously closed to afford the maximum efliciency.

After the fire in the stove is burning properly the damper 42 is closed and dampers 43 and 15 opened whereby the hot combustion products-Smoke and gases-from the stove are conducted through the duct 36 and fireplace 12 to the chimney flue 14L so that the heat from such. combustion products may be utilized in the fireplace for Warming the adjacent room. 7 1

Under the conditions above explained the hot air from the heating chamber may be caused to accompany the smoke by allowing the damper S9 to remain open, or the damper 39 may be closed and the hot air from the chamber 16 can be discharged through outlets 46,1 01 delivery through registers above mentioned.

While any suitable fuel can be used in the stove, best results are believed to be obtainable with wood fuel. 1

The operation and advantages of the invention will, it is thought, be understood from the foregoing description.

What I claim is,

7 1. In a chimney having a fireplace, a flue therefor, an air heating chamber, a second flue, and an inlet passage for said fireplace, a. stove provided in said chamber, a stove pipe connecting said stove with said second flue and alsowith said passage, a system of dampers provided for said pipe, and means for regulating said dampers whereby smoke products from the stove may be directed, selectively, into the second named flue or into said passage.

2. In a chimney having a fireplace, a flue therefor, an air heating chamber, a second flue, and an inlet passage for said fireplace, a stove provided in said chamber, a stove pipe connecting said stove with said second flue and also with said passage, said pipe having an air inlet communicating with the space in the chamber surrounding said pipe,

a system of dampers provided for said pipe, and means for regulating said dampers whereby smoke products from the stove may be directed, selectively, into the second named fiue or into said passage, said means also controlling the dampers to efi'ect the delivery of hot air into said passage from 7 said chamber accompanied by the smoke products from the stove.

3. In achnnneyhaving a fireplace, an air heating chamber below the fireplace, a passage vcommunicatively connecting said chamber with the fireplace, a stove provided in said chamber for heating the air in the latter, and means for regulating the admission oi air. into said passage from the chamber, and damper devices for controlling the combustion of fuel in the stove.

l. In a chimney having a fireplace, an air heating chamber below the fireplace, and a communicative connection between said chamber and the fireplace, a stove provided in said chamber, a stove pipe for said stove connnunicating with a flue of said chimney and also with said passage, said pipe having an all inlet from said chamber,-and a system of dampers provlded for said pipe whereby smoke from the stove maybe delivered selectively into said flue or into said passage, or air from said chamber delivered into the passage exclusive of smoke.

5. In a chimney having an open fireplace, 7

of the stove pipe, a hot air inlet providedfor the stove pipe intermediate the branches thereof, and a damper for said air inlet to regulate the effective size of the latter. 7
